DISCHARGE LOADING MEANS FUR TILE-CLEANING MACHINES.

Original application filed July 27, 1921,

This invention is a'loading means for a tile cleanlng machine whereby cleaned'tiles are delivered automatically nto receptacles in a manner to minimize breaking or chipacting mechanisms under conditions which, While effective in elimlnating the sand adhering to the tile material, at the same time avoids to a marked extent the breaking of the tiles or chipping the edges thereof.

The present invention embodies means for effecting the delivery of the tile material from the tumbling screen cylinder to a receptacle positioned at the off-take end of the machine, and the objects are, first, to load the cleaned tile product into the receptacle in a way to avoid breaking the tiles or chipping the edges thereof, and, second,.

to dispense withhand labor in such delivery. r

According to my invention, the loading mechanism embodies a movable carrier positioned for receiving the product from the treating mechanism, said carrier being depressible under the weight of the load as it accumulates within a receptacle adapted to be supported by the carrier, whereby the receptacle is maintained normallyin a de-' tel-mined relation to the treating mechanism to minimize the distance to be traveled by the product on its way from the treating mechanism into said receptacle.

In a preferred form, the depressible load carrier is pivoted for movement with respect to the treating mechanism, and is counterpoised so as to maintain said carrier at the required minimum distance from saidtreating mechanism. Cooperating, with said carrier is a latch or detent adapted for lock- 7 ing the carrier in alowered position, where by a loaded receptacle may be shifted from the carrier to a roller bed or conveyor and thus a filled receptacle may be replaced by an empty receptacle.

It is desirable to employ a conveyor bee Serial No. 487,854. Divided an 1925. Serial No. 23,594. 7

tween the load-receiving carrier and the tumbling screen cylinder, the latter constiproduct from said cylinder is deposited upon the conveyor and thus preliminarily spread out for'delivery into the receptacleof the depressible carrier.

Other functions and advantages of the tuting the treating mechanism. The cleaned invention will appear from the following description taken in connection with the drawings, wherein Figure '1 is a side elevation of a tile cleaning machine which includes a depressible load discharge mechanism of my invention. Figure 2 is a plan view with the screen cylinder of the treating mechanism omitted.

Figure 3 an end view illustrating the rear of the machine] Figure 4 is an enlarged side View, partly in section, showing the load-discharging means in a normal operative relation to the treating means.

Figure 5 is a vertical cross section on the line 5 5 of Figure 4.

The organized machine forcleaning tiles includes a feed hopper A, an inclined runway B, an elevator or conveyor C, a treating mechanism shown as a tile tumbling screen cylinder D, and the novel load-discharging mechanism which latter constitutes thesub ject-matter ofthepresent application.

As shown, the screen cylinder is provided with external bands (Z resting upon grooved rolls 2' provided on a plurality ofllongitudinal shafts FF, the latter extending lengths wise of a frame member a and inclined with reference thereto for supporting the treating cylinder D in an inclined position. The treating cylinder is open at the lower 'end' fofi'th'e free exit of the tile product adapted tobe tumbled'within the cylinder :by the rotative movement thereof For imparting rotative motion to the treating p a a cylinder, the sharts F F arerotated through bevel gears h-from a cross shaft E having a belt pulley E, and this cross shaft E is eared at r" to another cross shaft which b J y g latter is provided with a friction roller or pulley 6 adapted to drive the endless elevator or conveyor C, the latter operating to carry the product from hopper A and to deposit the samewithin the receiving end of the treating cylinder D..

J is the depressible carrier for receiving the load discharged from the treating mech the tacle upon the roller bed and in removing filled receptacles from the same: Interanism D. This carrier is shown as a plat form provided with a series of rollers J suitably journaled on the platform to extend crosswise thereof. The carrier is provided, also, with a plurality of arms m, m, which are made fast with a horizontal rock said treatingineans D the carrier is counterpoised, for which purpose the rock shaft m" is provided with an arm m towhich arm '18 plvoteda rod m which is equipped with a weight K, the ponderosity of which is sui'licient to "lift the carrier J and a receptacle intoclose relation to the discharge of the treating mechanism and which weightis overcome gradually by the accumulation of the 'load within said receptacle so that the carrier is depressed ultimately into an alined' position relative to the roller bed N. 'As shown, the roller table is a framework or bed'n with a series of idle rolls 72x61 tending crosswise of, the path of material passing throughthe treating machine, saidb rol-ler tablebeing at a height: convenient to attendant 1n placing an empty recep mediate. its ends, the frame or bed a of the roller table is provided with a recessn into which the depressible carrier J is adapted to move under the weight of the load accumulated in the receptacle, indicated by the dotted vline atiL in Figure VVhenthus lowered, the depressible carrier J is in a flush relation to the rollerbed N and the rollers J of said carrier are in the plane,

substantially, ofjthe rollers 42. of the bed, See full lines in Figure 3, whereby a filled or loaded'receptacle Lon the carrier may be slid olfthe rolls J of the carrier onto the rolls nfof the'bed, and in like manner an empty receptacle onthe roller bed i? may be shifted from said bed onto therolle'rs" of the depressible carrier.

For locking the carrier 7 vide one side of the carrier and adapted for loclo detent is pivoted at its lower end to a release lever or treadle O,'hung at 0 intermediateits ends on the lower part of the frame member aE-and the inner end of which lever is counterpoised by weight see Figure 4. A downward movement of the free end of lever or treadle O withdraws the latch or detent o from engagement'with the carrier, J, whereupon the counterpoise K'swings'the carrier, and an empty recepcharge of the treating mechanism.

7 p "with a loaded re- 'ceptacle m the lowermost position, 1 pr "kiln and a latch or detent 0, extending vertically at .tacle on said carrier, in an upward direc tion and thus restores the carrier to the de sired normal operative relation to the dis- As illustrated, the loading carrier is at a distance from the delivery end of the treating cylinder D,,and to bridge the space between J and D, there is provided a chute H and an endless conveyor I, although these elements H I may be dispensed with by coordinating the carrier J in operative relation to the cylinder D for loading the prod-.

not from one to the other directly.

lhe chute H is supported in a fixed position Within the frame member a and is inclined slightly from the screen cylinder D to an overhanging relation to the depressible carrierJ and its receptaclejL. As shown, the chute is provided With raised sides and a raised'uloading end, but the bottom H of said chute is perforated awe, in Figure 5,

for the .free'ex'it of sand which, with the cleaned tile product, is discharged from'the open end of the inclined screen cylinder D. The conveyor-I 1S shownin operatlve re;

lation to the chute, for the upper lead or,

run of said conveyor to traverse the perforated bottom H of said chute, The length of the conveyor exceeds the length of the chute, and said conveyor is supported by rollers-or pulleys .y' y", positioned beyond the respective end portiens'of said chute, see Figure 4. The rollerj'. is an idler on a shaft journaled in a bracket 7" of the frame member a whereas the roller j constitutes lot means for driving the conveyor because said roller jis fast with across shaft 70, journaled 1n bearings of 1 the frame member and which cross shaft is is operated by bevel gears 76 from a countersliaft 70 \vhlclrar. turn 1s drlven bysprocket gearing 70 from one of the two longitudinal shafts F. Provision is thus made for imparting traveling 111051011130 the conveyor I adapted for carry-' ing the material' discharged from the treating cylinder D into therec'eptacle L on the depressible carrier J.

"The operation will be apparentfrom' the foregoing 'descriptiom'but may be recited briefly as follows :Saggers loaded with burned tiles and sand are carried from a upon the conveyor, or elevator C carries the p tiles and sand from said hopper and Y (le mg engagement therewith. This latch on posit'sthe same within the screen D. The

rubbed to free them from the sand adhering j to the surfaces thereof. -Thesand makesits exit from the cylinder D and some of it dumped into the hopper A, where escapes from the conveyor C, but the tiles in j a cleaned'condition are delivered from the rear open end of the cylinder upon the conveyorl Whichwith the chute deposits the tiles into the receptacle L on the depressible carrier J the same being in a close normal relation to the delivery end portions of the conveyor I and the chute H. As the tiles accumulate within the receptacle L, the increase in the weight of the load depresses the pivoted carrier J and lifts the counterpoise K, and this depression otthe carrier is continned during the deposit of the material roller table'on one side or the other of such table, the rollers facilitating the movement.

of the loaded receptacle, and thereafter an empty receptacle is positioned upon the carrier, and the latch is released, so that the counterpoise will act to swing tne carrier upwardly and present the empty receptacle into loading relation to the chute and the conveyor.

In the loading mechanism of my invention the carrier supports a receptacle in a. position close to the conveyor, and this carrier is depressed gradually by the accumulation within the receptacle, whereby the slowly descending carrier minimizes the distance through which the tiles descend from the conveyor until they lodge upon the pile growing withinthe receptacle, thus reduc- .ing to a minimum the liability o't'breaking the tiles or of chipping the edges thereof.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is: V
